/**

 * Create a synthetic DOCX fixture for a table row made only of vertical-merge

 * continuation cells.

 *

 * The generated document uses neutral sample text. It reproduces DOCX tables

 * that can parse into a row where every cell has <w:vMerge/> and no cell would

 * be emitted after ProseMirror row-span collapsing.

 *

 * Run: bun scripts/create-empty-table-row-vmerge-fixture.mjs
